25. Nice rant

but there is nothing "reasonable" about the absolutist nature of your premise. There are any number of scenarios where using lethal force in self defense that results in killing an unarmed "child" may meet the legal standard for being "reasonable".

Let's say a 17 year old male "child" breaks into the apartment of a single female and try's to rape her, after hitting her a few times. If the victim can get their hands on a knife or a gun or some other weapon and used it to stop the assault by killing her attacker, my guess is that most people would find the killing of an unarmed "child" to be a pretty reasonable response in that scenario.

Whether or not Zimmerman's actions reach the level of reasonable self defense is up to the jury to decide.
